I'm finding it quite difficult to nail down wire size specification for DC Circuit Breakers. I'm most interested in the type we see in PV Combiner Boxes on Amazon as well as WATTS247.com. I've sent queries to several vendors. Anyone on here with hands on experience?
I'm running AWG 4 wire 50 feet x 2 from my charge controller to a future 12V PV panel install. All my gear is 12V and that is not going to change.
So can anyone tell me if AWG 4 wire will fit into a typical DC Circuit breaker? I've seen youtube videos where it was mentioned they were using AWG 4
wire but I'm having doubts.
This all affects which combiner box I use because, if I need to add a small bus bar to change wire size, the box will need the room.
